Revision Standard – Active. This IEEE Standards product is part of the C57 family on Power Distribution and Regulating Transformers. Recommendations believed essential for the application of overcurrent protective devices applied to limit the exposure time of transformers to short-circuit current are set forth. Transformer coordination curves are presented for four categories of transformers. There is no intent to imply overload capability<\/p>\n
